80. Advertisement: Clark brand-name parts are made for cars manufactured in this country. They satisfy all of our government automotive tests-the toughest such tests in the world. With foreign-made parts, you never know which might be reliable and which

are cheap look-alikes that are poorly constructed and liable to cost you hundreds of dollars in repairs. Therefore, be smart and insist on brand-name parts by Clark for your car.

The argument requires the assumption that

A.        Clark parts are available only in this country

B.        foreign-made arts are not suitable for cars manufactured in this country

C.        no foreign-made parts satisfy our government standards

D.       parts that satisfy or government standards are not as poorly constructed as cheap foreign made parts

E.        if parts are made for cars manufactured in our country, they are not poorly constructed

参考答案：D

思路：C东东通过了G test, 所以，选C东东，不选国外东东。

A.        无关，而且有only,

B.         加强。

C.         无关。用不用G和国外的与satisfy standards 无关。

D.        取非。通过了test的G与国外的一样。削弱加强。
